Function for parsing email

Hello All, I'm trying to find a classs/script which allows me to parse an incoming email. I have seen many older scripts/classes but wanted to see if there is maybe something newer. I don't want to use a whole framework etc. I know how to get the message from the mail server to pipe to my application We will take from the incoming messages everything available including attachments(multiple) and process based on that content. I appreciate your help!!!
